Open letters seem to be all the rage these days. How about we just go with "Craig, as benevolent dictator, says How It Is":
Microsoft are hereby instructed to publish Open Office XML as a royalty and patent free open standard. Everyone else is hereby instructed to change to use it (they can call it OpenDocument 2.0 if required), and then people won't have to care about OpenOffice.org if they don't want, because the standard is standard.
Microsoft will then be forced to operate exactly to the published standard, publishing changes under the same license and arrangement if they wish to extend the standard (well before the release of their product), and maintaining backwards compatibility.
There, everyone wins. Why does it always take me deciding how it has to be, to get results like this?
